Hello, can someone please help me understand if specific labor categories are required to award an FFP LOE TO? I have researched FFP LOE and gather that rates are not involved and the Gov is awarding a FFP for an amount of labor (hours in this case); however, we are stuck on whether or not the contract can just be for hours and use the expected number and labor categories for negotiation purposes or if the exact labor hours in the contract needs to be broken down into number of workers in each category. Ideally, the former would be true so that the contractor has the flexibility to change the labor categories if need be (as long as the hours don't change) without the need for a mod. Thank you in advance!
